ToolStrip.ItemAdded Event

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Occurs when a new ToolStripItem is added to the ToolStripItemCollection.

public:
 event System::Windows::Forms::ToolStripItemEventHandler ^ ItemAdded;

public event System.Windows.Forms.ToolStripItemEventHandler? ItemAdded;

member this.ItemAdded : System.Windows.Forms.ToolStripItemEventHandler 

Public Custom Event ItemAdded As ToolStripItemEventHandler 

Event Type

ToolStripItemEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ItemAdded event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type ToolStrip named ToolStrip1. Then ensure that the event handler is associated with the ItemAdded event.

private void ToolStrip1_ItemAdded(Object sender, ToolStripItemEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ItemAdded Event" );
}

Private Sub ToolStrip1_ItemAdded(sender as Object, e as ToolStripItemEventArgs) _ 
     Handles ToolStrip1.ItemAdded

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ItemAdded Event")

End Sub
